The ACE (American Council on Education) recommends 6 lower level college credits for this exam.

Studying, and passing, the practice tests below will allow you to confidently take and pass your Biology Clep test. The overall key concepts, and specific individual points, that will allow you to pass your test are within the practice questions and detailed explanations.


Course Information and Overview

This exam covers material that is typically taught in a one-year introductory-level college course. The multiple-choice CLEP exam consists of 115 questions and allows 90 minutes to complete. 

The exam will be testing your skills related to your knowledge of Biology including your knowledge of the processes, principles, and facts of biology, your understanding of information collection, interpretation, and hypotheses, and your understanding of biology as an endeavor with social consequences.

Many schools award six semester hours for this exam since it is the equivalent to a full-year course.  Check with your college to verify the credits awarded.
